WARNING : It indicates that incorrect use of this unit may cause severe injury or death. CAUTION : FAILURE TO FOLLOW THIS CAUTION may result in equipment damage or improper operation and personal injury. • • CAUTION New refrigerant air conditioner installation • • THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER. R410A refrigerant is affected by inpurities such as water and oils because the pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. ALSO NEW OILS ARE USED WITH R410A, THUS ALWAYS USE NEW REFRIGERANT PIPING AND DO NOT ALLOW MOISTURE OR DUST TO ENTER THE SYSTEM. To avoid mixing refrigerant and refrigerant machine oil, the sizes of charging port on the main unit is different than those used on R22 machines and different tools will be required. EQUIPMENT DAMAGE HAZARD Failure to follow this caution may result in equipment damage or improper operation. Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is buried, there must be a 6 in. (152 mm) vertical rise to the valve connections on the outdoor units. If more than the recommended length is buried, refrigerant may migrate to the cooter buried section during extended periods of system shutdown. This causes refrigerant slugging and could possibly damage the compressor at start-up. − 3− FILE NO. SVM-13069 DANGER • • • • • • • • FOR USE BY QUALIFIED PERSONS ONLY. TURN OFF MAIN POWER SUPPLY BEFORE.ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF. FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK. CONNECT THE CONNECTING CABLE CORRECTLY.

REFRIGERANT R410A This air conditioner adopts the new refrigerant HFC (R410A) which does not damage the ozone layer. The working pressure of the new refrigerant R410A is 1.6 times higher than conventional refrigerant (R22). The refrigerating oil is also changed in accordance with change of refrigerant, so be careful that water, dust, and existing refrigerant or refrigerating oil are not entered in the refrigerant cycle of the air conditioner using the new refrigerant during installation work or servicing time. The next section describes the precautions for air conditioner using the new refrigerant. Conforming to contents of the next section together with the general cautions included in this manual, perform the correct and safe work. FILE NO. SVM-13069 6. When an air conditioning system charged with a large volume of refrigerant is installed in a small room, it is necessary to exercise care so that, even when refrigerant leaks, its concentration does not exceed the marginal level. If the refrigerant gas leakage occurs and its concentration exceeds the marginal level, an oxygen starvation accident may result. 7. Be sure to carry out installation or removal according to the installation manual. Improper installation may cause refrigeration trouble, water leakage, electric shock, fire, etc. 8. Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a qualified air conditioner technician or electrician. Improper repair’s may result in water leakage, electric shock and fire, etc. 3-1. Safety During Installation/Servicing As R410A’s pressure is about 1.6 times higher than that of R22, improper installation/servicing may cause a serious trouble. By using tools and materials exclusive for R410A, it is necessary to carry out installation/servicing safely while taking the following precautions into consideration. 1. Never use refrigerant other than R410A in an air conditioner which is designed to operate with R410A. If other refrigerant than R410A is mixed, pressure in the refrigeration cycle becomes abnormally high, and it may cause personal injury, etc. by a rupture. 2. Confirm the used refrigerant name, and use tools and materials exclusive for the refrigerant R410A. The refrigerant name R410A is indicated on the visible place of the outdoor unit of the air conditioner using R410A as refrigerant. To prevent mischarging, the diameter of the service port differs from that of R22. 3. If a refrigeration gas leakage occurs during installation/servicing, be sure to ventilate fully. If the refrigerant gas comes into contact with fire, a poisonous gas may occur. 4. When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigeration cycle. Otherwise, pressure in the refrigeration cycle may become abnormally high so that a rupture or personal injury may be caused. 5. After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas leaks into the room, coming into contact with fire in the fan-driven heater, space heater, etc., a poisonous gas may occur. 3-2. Refrigerant Piping Installation 3-2-1. Piping Materials and Joints Used For the refrigerant piping installation, copper pipes and joints are mainly used. Copper pipes and joints suitable for the refrigerant must be chosen and installed. Furthermore, it is necessary to use clean copper pipes and joints whose interior surfaces are less affected by contaminants. 1. Copper Pipes It is necessary to use seamless copper pipes which are made of either copper or copper alloy and it is desirable that the amount of residual oil is less than 40 mg/10 m. Do not use copper pipes having a collapsed, deformed or discolored portion (especially on the interior surface). Otherwise, the expansion valve or capillary tube may become blocked with contaminants. As an air conditioner using R410A incurs pressure higher than when using R22, it is necessary to choose adequate materials. Thicknesses of copper pipes used with R410A are as shown in Table 3-2-1. Never use copper pipes thinner than 0.0315 in. (0.8 mm) even when it is available on the market. –8– FILE NO. SVM-13069 Table 3-2-1 Thicknesses of annealed copper pipes Thickness in.

Joints For copper pipes, flare joints or socket joints are used. Prior to use, be sure to remove all contaminants. a) Flare Joints Flare joints used to connect the copper pipes cannot be used for pipings whose outer diameter exceeds 20 mm. In such a case, socket joints can be used. Sizes of flare pipe ends, flare joint ends and flare nuts are as shown in Tables 3-2-3 to 3-2-6 below. b) Socket Joints Socket joints are such that they are brazed for connections, and used mainly for thick pipings whose diameter is larger than 0.7874 in. (20 mm). Thicknesses of socket joints are as shown in Table 3-2-2.

Processing of Piping Materials When performing the refrigerant piping installation, care should be taken to ensure that water or dust does not enter the pipe interior, that no other oil than lubricating oils used in the installed air-water heat pump is used, and that refrigerant does not leak. When using lubricating oils in the piping processing, use such lubricating oils whose water content has been removed. When stored, be sure to seal the container with an airtight cap or any other cover. 1. Flare processing procedures and precautions a) Cutting the Pipe By means of a pipe cutter, slowly cut the pipe so that it is not deformed. b) Removing Burrs and Chips If the flared section has chips or burrs, refrigerant leakage may occur. Carefully remove all burrs and clean the cut surface before installation. c) Insertion of Flare Nut –9– FILE NO. SVM-13069 d) Flare Processing Make certain that a clamp bar and copper pipe have been cleaned. By means of the clamp bar, perform the flare processing correctly. Use either a flare tool for R410A or conventional flare tool. Flare processing dimensions differ according to the type of flare tool. When using a conventional flare tool, be sure to secure “dimension A” by using a gauge for size adjustment.

To reinforce the pressure-resisting strength, flare processing dimensions and opposite side dimension of flare nut (For ∅ 1/2 in. 12.7mm) copper pipe) of the refrigerant piping are lengthened. The used refrigerating oil is changed, and mixing of oil may cause a trouble such as generation of sludge, clogging of capillary, etc. Accordingly, the tools to be used are classified into the following three types. 1.

Recharging of Refrigerant When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the following steps. Recover the refrigerant, and check no refrigerant remains in the equipment. When the compound gauge’s pointer has indicated − 14.7 Psi (–0.1 Mpa) or − 29.9 inHg (–76 cmHg), place the handle Low in the fully closed position, and turn off the vacuum pump's power switch. Connect the charge hose to packed valve service port at the outdoor unit’s gas side. Keep the status as it is for 1 to 2 minutes, and ensure that the compound gauge’s pointer does not return. Connect the charge hose to the vacuum pump adapter. Set the refrigerant cylinder to the electronic balance, connect the connecting hose to the cylinder and the connecting port of the electronic balance, and charge liquid refrigerant. Open fully both packed valves at liquid and gas sides. (For refrigerant charging, see the figure below.) Place the handle of the gauge manifold Low in the fully opened position, and turn on the vacuum pump’s power switch. Then, evacuating the refrigerant in the cycle. 1. Never charge refrigerant exceeding the specified amount. 2. If the specified amount of refrigerant cannot be charged, charge refrigerant bit by bit in COOL mode. 3. Do not carry out additional charging. When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in the refrigeration cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the specified amount is charged, and working pressure in the refrigeration cycle becomes abnormally high pressure, and may cause a rupture or personal injury.

SVM-13069 1. Be sure to make setting so that liquid can be charged. 2. When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down. It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant. Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the cylinder upside down if cylinder is not equipped with siphon. [ Cylinder with siphon ] Gauge manifold OUTDOOR unit OUTDOOR unit Refrigerant cylinder Gauge manifold [ Cylinder without siphon ] Refrigerant cylinder Electronic balance Electronic balance Siphon R410A refrigerant is HFC mixed refrigerant. Therefore, if it is charged with gas, the composition of the charged refrigerant changes and the characteristics of the equipment varies. Fig. 3-4-2 3-5. Brazing of Pipes 1. Phosphor bronze brazing filler tends to react with sulfur and produce a fragile compound water solution, which may cause a gas leakage. Therefore, use any other type of brazing filler at a hot spring resort, etc., and coat the surface with a paint. 2. When performing brazing again at time of servicing, use the same type of brazing filler. 3-5-1. Materials for Brazing 1. Silver brazing filler Silver brazing filler is an alloy mainly composed of silver and copper. It is used to join iron, copper or copper alloy, and is relatively expensive though it excels in solderability. 2. Phosphor bronze brazing filler Phosphor bronze brazing filler is generally used to join copper or copper alloy. 3. Low temperature brazing filler Low temperature brazing filler is generally called solder, and is an alloy of tin and lead. Since it is weak in adhesive strength, do not use it for refrigerant pipes. 3-5-2. Flux 1. Reason why flux is necessary • By removing the oxide film and any foreign matter on the metal surface, it assists the flow of brazing filler. • In the brazing process, it prevents the metal surface from being oxidized. • By reducing the brazing filler’s surface tension, the brazing filler adheres better to the treated metal. – 14 – 2. Characteristics required for flux • Activated temperature of flux coincides with the brazing temperature. • Due to a wide effective temperature range, flux is hard to carbonize. • It is easy to remove slag after brazing. • The corrosive action to the treated metal and brazing filler is minimum. • It excels in coating performance and is harmless to the human body. As the flux works in a complicated manner as described above, it is necessary to select an adequate type of flux according to the type and shape of treated metal, type of brazing filler and brazing method, etc. 3. Types of flux • Noncorrosive flux Generally, it is a compound of borax and boric acid. It is effective in case where the brazing temperature is higher than 1472°F (800°C). • Activated flux Most of fluxes generally used for silver brazing are this type. It features an increased oxide film removing capability due to the addition of compounds such as potassium fluoride, potassium chloride and sodium fluoride to the borax-boric acid compound. 4.

Brazing FILE NO. SVM-13069 As brazing work requires sophisticated techniques, experiences based upon a theoretical knowledge, it must be performed by a person qualified. In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry Nitrogen gas (N2) flow. Never use gas other than Nitrogen gas. 1. Brazing method to prevent oxidation 1) Attach a reducing valve and a flow-meter to the Nitrogen gas cylinder. 2) Use a copper pipe to direct the piping material, and attach a flow-meter to the cylinder. 3) Apply a seal onto the clearance between the piping material and inserted copper pipe for Nitrogen in order to prevent backflow of the Nitrogen gas. 4) When the Nitrogen gas is flowing, be sure to keep the piping end open. 5) Adjust the flow rate of Nitrogen gas so that it is lower than 0.03 cfm (0.05 m3/Hr) or 2.9 Psi (0.02 MPa) by means of the reducing valve. 6) After performing the steps above, keep the Nitrogen gas flowing until the pipe cools down to a certain extent (temperature at which pipes are touchable with hands). 7) Remove the flux completely after brazing. M Flow meter Stop valve Nitrogen gas cylinder 1. Do not enter flux into the refrigeration cycle. 2. When chlorine contained in the flux remains within the pipe, the lubricating oil deteriorates. Therefore, use a flux which does not contain chlorine. 3. When adding water to the flux, use water which does not contain chlorine (e.g. distilled water or ion-exchange water). 4. Remove the flux after brazing. From Nitrogen cylinder Pipe Nitrogen gas Rubber plug Fig. 3-5-1 Prevention of oxidation during brazing – 15 – 4. CONSTRUCTION VIEWS FILE NO. SVM-13069-3 4-1.

Outline of Air Conditioner Control This air conditioner is a capacity-variable type air conditioner, which uses AC or DC motor for the indoor for motor and the outdoor fan motor. And the capacityproportional control compressor which can change the motor speed in the range from 11 to 96 rps is mounted. The DC motor drive circuit is mounted to the indoor unit. The compressor and the inverter to control fan motor are mounted to the outdoor unit. The entire air conditioner is mainly controlled by the indoor unit controller. The indoor unit controller drives the indoor fan motor based upon command sent from the remote controller, and transfers the operation command to the outdoor unit controller. The outdoor unit controller receives operation command from the indoor unit side, and controls the outdoor fan and the pulse Modulating valve. (P.M.V) Besides, detecting revolution position of the compressor motor, the outdoor unit controller controls speed of the compressor motor by controlling output voltage of the inverter and switching timing of the supply power (current transfer timing) so that motors drive according to the operation command. And then, the outdoor unit controller transfers reversely the operating status information of the outdoor unit to control the indoor unit controller. • Detection of inverter input current and current release operation • Over-current detection and prevention operation to IGBT module (Compressor stop function) • Compressor and outdoor fan stop function when serial signal is off (when the serial signal does not reach the board assembly of outdoor control by trouble of the signal system) • Transferring of operation information (Serial signal) from outdoor unit controller to indoor unit controller • Detection of outdoor temperature and operation revolution control • Defrost control in heating operation (Temp. measurement by outdoor heat exchanger and control for 4-way valve and outdoor fan) 3. Contents of operation command signal (Serial signal) from indoor unit controller to outdoor unit controller The following three types of signals are sent from the indoor unit controller. • Operation mode set on the remote controller • Compressor revolution command signal defined by indoor temperature and set temperature (Correction along with variation of room temperature and correction of indoor heat exchanger temperature are added.) • Temperature of indoor heat exchanger • For these signals ([Operation mode] and [Compressor revolution] indoor heat exchanger temperature), the outdoor unit controller monitors the input current to the inverter, and performs the followed operation within the range that current does not exceed the allowable value. As the compressor adopts four-pole brushless DC motor, the frequency of the supply power from inverter to compressor is two-times cycles of the actual number of revolution. 1. Role of indoor unit controller The indoor unit controller judges the operation commands from the remote controller and assumes the following functions. • Judgment of suction air temperature of the indoor heat exchanger by using the indoor temp. sensor. (TA sensor) • Judgment of the indoor heat exchanger temperature by using heat exchanger sensor (TC sensor) (Prevent-freezing control, etc.) • Louver motor control • Indoor fan motor operation control • LED (Light Emitting Diode) display control • Transferring of operation command signal (Serial signal) to the outdoor unit • Reception of information of operation status (Serial signal including outside temp. data) to the outdoor unit and judgment/display of error • Air purifier operation control FILE NO. SVM-13069 4. Contents of operation command signal (Serial signal) from outdoor unit controller to indoor unit controller 2. Role of outdoor unit controller The following signals are sent from the outdoor unit controller. • The current operation mode • The current compressor revolution • Outdoor temperature • Existence of protective circuit operation For transferring of these signals, the indoor unit controller monitors the contents of signals, and judges existence of trouble occurrence. Contents of judgment are described below. • Whether distinction of the current operation status meets to the operation command signal • Whether protective circuit operates When no signal is received from the outdoor unit controller, it is assumed as a trouble. Receiving the operation command signal (Serial signal) from the indoor unit controller, the outdoor unit performs its role. • Compressor operation control • Operation control of outdoor fan motor Operations followed to judgment of serial signal from indoor side. • P.M.V. control • 4-way valve control – 28 – FILE NO.

Installation/Servicing Tools Changes in the product and components In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, the service port diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch) • In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8) New tools for R410A New tools for R410A Applicable to R22 model Changes Gauge manifold × As pressure is high, it is impossible to measure by means of conventional gauge. In order to prevent any other refrigerant from being charged, each port diameter has been changed. Charge hose × In order to increase pressure resisting strength, hose materials and port size have been changed (to 1/2 UNF 20 threads per inch). When purchasing a charge hose, be sure to confirm the port size. Electronic balance for refrigerant charging ¡ As pressure is high and gasification speed is fast, it is difficult to read the indicated value by means of charging cylinder, as air bubbles occur. Torque wrench (nominal diam. 1/2, 5/8) × The size of opposite sides of flare nuts have been increased. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8. Flare tool (clutch type) Gauge for projection adjustment By increasing the clamp bar’s receiving hole, strength of spring in the tool has been improved. ¡ — — Used when flare is made by using conventional flare tool. Vacuum pump adapter ¡ Connected to conventional vacuum pump. It is necessary to use an adapter to prevent vacuum pump oil from flowing back to the charge hose. The charge hose connecting part has two ports-one for conventional refrigerant (7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes with R410A a sludge may occur and damage the equipment. Gas leakage detector × Exclusive for HFC refrigerant. • Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the U. S’s ARI specified rose color (ARI color code: PMS 507). • Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to the charge hose’s port size. – 56 – FILE NO.

SVM-13069 CAUTION A high voltage (equivalent to the supply voltage) is also energized to ground through the sensors, PMV and other low-voltage circuits. The sensor leads and other wires are covered with insulated tubes for protection. Nevertheless, care must be taken to ensure that these wires are not pinched. Take sufficient care to avoid directly touching any of the circuit parts without first turning off the power. At times such as when the circuit board is to be replaced, place the circuit board assembly in a vertical position. Laying the board flat on an electrically conductive object (such as the top panel of the air conditioner's outdoor unit) while a charge is still retained by the electrolytic capacitors of the inverter's main circuit may cause short-circuiting between the electrolytic capacitors and secondary circuit components and result in damage to the components. Sensor leads Fig. 11-2 Do NOT lay the circuit board assembly flat. K Precautions when inspecting the control section of the outdoor unit NOTE : A large-capacity electrolytic capacitor is used in the outdoor unit controller (inverter). Therefore, if the power supply is turned off, charge (charging voltage DC265 to 360V) remains and discharging takes a lot of time. After turning off the power source, if touching the charging section before discharging, an electrical shock may be caused. Discharge the electrolytic capacitor completely by using soldering iron, etc. < Discharging method > 1. Remove the inverter cover (plating) by opening four mounting claws. 2. As shown below, connect the discharge resistance (approx. 100Ω40W) or plug of the soldering iron to voltage between + – terminals of the C14 (“CAUTION HIGH VOLTAGE” is indicated.) electrolytic capacitor (500µF/400V) on P.C. board, and then perform discharging.

Operation Which is not a Trouble (Program Operation) For controlling the air conditioner, the program operations are built in the microcomputer as described in the following table. If a claim is made for running operation, check whether or not it meets to the contents in the following table. When it does, we inform you that it is not trouble of equipment, but it is indispensable for controlling and maintaining of air conditioner. Table 11-1-1 No. Operation of air conditioner Description 1 When power breaker is turned “ON”, the operation indicator (Green) of the indoor unit flashes. The OPERATION lamp of the indoor unit flashes when power source is turned on. If [ ] button is operated once, flashing stops. (Flashes also in power failure) 2 Compressor may not operate even if the room temperature is within range of compressor-ON. The compressor does not operate while compressor restart delay timer (3-minutes timer) operates. The same phenomenon is found after power source has been turned on because 3-minutes timer operates. 3 In Dry and ECO mode, FAN (air flow) display does not change even though FAN (air flow select) button is operated. The air flow indication is fixed to [AUTO]. 4 Increasing of compressor motor speed stops approx. 30 seconds after operation started, and then compressor motor speed increases again approx. 30 seconds after. For smooth operation of the compressor, the compressor motor speed is restricted to Max. 41 rps for 2 minutes, and Max.91 rps for 2 minutes to 3 minutes, respectively after the operation has started. 5 In AUTO mode, the operation mode is changed. After selecting Cool or Heat mode, select an operation mode again if the compressor keeps stop status for 15 minutes. 6 In HEAT mode, the compressor motor speed does not increase up to the maximum speed or decreases before the temperature arrives at the set temperature. The compressor motor speed may decrease by hightemp. release control (Release protective operation by temp.-up of the indoor heat exchanger) or current release control. – 72 – FILE NO.

Symptom • Outdoor fan motor does not rotate. • Outdoor fan motor stops within several tens seconds though it started rotating. • Outdoor fan motor rotates or does not rotate according to the position where the fan stopped, etc. Remote controller check code “02 : Outdoor block, 1A : Outdoor fan drive system error” 2. Cause The following causes are considered when the outdoor fan motor does not normally rotate. 1) Mechanical lock of the outdoor fan motor 2) Winding failure of the outdoor fan motor 3) Position-detect circuit failure inside of the outdoor fan motor 4) Motor drive circuit failure of the outdoor P.C. board 3. How to simply judge whether outdoor fan motor is good or bad Turn OFF the breaker. Disconnect two connectors (CN300) of the outdoor fan motor from the outdoor P.C. board. Does the fan rotate without trouble when rotating it with hands? NO CN300 YES If the resistance value between 1 (Red lead) – 2 (White lead) 2 (White lead) – 3 (Black lead) 3 (Black lead) – 1 (Red lead) of the connector (CN300 : Motor winding) is 17 to 25Ω, it is normal. NO YES Fan motor is normal. Fan motor error (Outdoor P.C. board error) NOTE : However, GND circuit error inside of the motor may be accepted in some cases when the above check is performed. When the fan motor does not become normal even if P.C. board is replaced, replace the outdoor fan motor. – 96 – FILE NO. SVM-13069 12. HOW TO REPLACE THE MAIN PARTS WARNING • Since high voltages pass through the electrical parts, turn off the power without fail before proceeding with the repairs. Electric shocks may occur if the power plug is not disconnected. • After the repairs have been completed (after the front panel and cabinet have been installed), perform a test run, and check for smoking, unusual sounds and other abnormalities. If this check is omitted, a fire and/or electric shocks may occur. Before proceeding with the test run, install the front panel and cabinet. • Ensure that the following steps are taken when doing repairs on the refrigerating cycle. 1. Do not allow any naked flames in the surrounding area. If a gas stove or other appliance is being used, extinguish the flames before proceeding. If the flames are not extinguished, they may ignite any oil mixed with the refrigerant gas. 2. Do not use welding equipment in an airtight room. Carbon monoxide poisoning may result if the room is not properly ventilated. 3. Do not bring welding equipment near flammable objects. Flames from the equipment may cause the flammable objects to catch fire. • If keeping the power on is absolutely unavoidable while doing a job such as inspecting the circuitry, wear rubber gloves to avoid contact with the live parts. Electric shocks may be received if the live parts are touched. High-voltage circuits are contained inside this unit. Proceed very carefully when conducting checks since directly touching the parts on the control circuit board may result in electric shocks. 12-1.
